Tomas,

The scanner was replugged but the only time I reboot the server/workstation
is after a kernel upgrade.

The same versions of sane and xsane were re-installed.

Nope. My backup is scangearmp2-3.70-1 and it works. Xsane worked a couple of
months ago and I checked by LQ thread on the problem but didn't post the
actual solution.

The sane supported devices page shows the CanoScan LiDE 400 completely
supported with pixma-0.27.0 and I have -0.34.0 installed.

Thanks,

Rich
